Abstract: The present invention provides a carrier capable of highly efficiently introducing a compound into cells with low cytotoxicity, which contains peptide lipids represented by the following formula, and a method for introducing a compound into cells using the carrier: wherein R1 is an amino acid or peptide having 1-10 amino acid residues, R2 is a side chain of any amino acid, provided that R2 has a carboxyl group, the carboxyl group may be an ester with a hydrocarbon group having 1-30 carbon atoms, R3 is a hydrocarbon group having 1-30 carbon atoms.

Abstract: Embodiments of the present invention are directed to methods and systems of storing data in storage volumes while ensuring data matching between the storage volumes. In one embodiment, a system for storing data comprises a first storage area to store data, a second storage area to store data, a first storage control unit configured to control the first storage area, and a second storage control unit configured to control the second storage area. In response to a first write request issued to write data in the first storage area, the first storage control unit is configured to write data associated with the first write request to the first storage area and to transfer the first write request to the second storage control unit, and the second storage control unit is configured to write the data associated with the first write request to the second storage area.

Abstract: The present invention allows a reserved state that prevails for an LDEV as a result of a host undergoing a system shutdown or the like to be confirmed and cancelled easily. The server 1 reserves the LDEV 4 and uses same exclusively. When the server 1 undergoes a system shutdown due to a fault or similar (S1), the LDEV 4 then remains reserved (S2). The server 2 is therefore unable to access the LDEV 4. The system administrator reads exclusive control information 6 in the memory 5 via the management terminal 7, and is thus able to display the reserved states of respective LDEVs on a terminal screen and confirm these states. The user then issues an instruction to cancel a reserved state from the management terminal 7 (S3). The disk array device 3 receives the cancellation instruction, and then cancels the reserved state by partially rewriting the exclusive control information 6.

Abstract: In response to requests for I/O processing sent from a computer, I/O which should be processed at a priority is enabled to be processed without being affected by other processing, by classifying I/O into those to be processed at a priority and those not to be processed at a priority. The storage control apparatus comprises an I/O processing controller with a memory that is common for the whole controller. The storage control apparatus manages information for dividing and controlling a plurality of I/O processes as priority and non-priority in that memory and operates while suppressing non-priority I/O processing on the basis of information in the memory.

Abstract: A storage controller can perform backup processing without proceeding via a server and without the need for the server to grasp the state of pair volumes. When an instruction for backup is given from the server while data is being copied from a source volume to a target volume, the storage controller transfers the data to a backup device using differential information between the pair volumes after waiting until data about a range to be backed up and instructed by the server is copied into the target volume.
